The silver Y produces several (overlapping) generations a year. The caterpillars, which feed on clover and various vegetables, overwinter in a kind of cocoon. | | |

...the middle is the characteristic leaf-like marking (folium). It is composed of a white surrounding area against the broad and clearly visible, greenish-brown or brownish-gold coloured band with a fine dark network of lines on the surface. A shiny silver-whitish area can be on its front section. The folium in space is limited by deep waves with narrow dark edges which can be golden , bronze or brownish in colour. The underside of the opisthosoma is dark brown and shiny silver with two narrow bands running lengthwise, which stop at the spider’s silk-spinning organ (spinneret). | | |
| | Adult Autographa gamma reach wingspans of 35 - 40 mm. Their forewings are grey to dark grey and have a dark marking. In the mid-wing area is a bright marking shaped like a bent "Y". The hindwings are greyish-brown with dark edges. The silver Y has a very long proboscis and can suck nectar out from deep flower calyx. The caterpillars, which are up to 25 mm in length, are light green and have a pattern of fine bright lines on their back. | | |
